Abstract — The sequence in which the elements are dissolved from ferrite–perlite alloys in oxalate media is found. A part of the cementite phase in the salt passivation accompanied by the appearance of several anodic current peaks in the passive range is demonstrated. The peaks are identified and shown to depend on the carbon-containing phase content.
